Lupex is a slow speed contact fibre paper made with a silver chloride emulsion and replaces Kodak Azo or Fomalux.
The speed is about 8 stops lower than MCC but therefore it is extremely finegrained and yields a superior resolution just like your large format negatives.
In contact printing the photographer is working with a stronger lightsource and without an enlarger (the large format film is placed directly on the paper) therefore you can work comfortably with this speed and have just enough time to burn in an dodge.
